Thanks David and Harry, I think the best option is to make a PCB with both msp430f149 and msp430f123 (I do not have size mecanical limits), then I can put just one of them. Then I can try to use f123 and if it "fails", I can continue with the f149.
Sure, it is better to run in a clock multiple of 115200 near 8MHz than runnint at axactly 8MHz. The packages are small. 16 bytes is the greater package, then I think f123 ram is enough. Another option that I tought is to use two f123, which is cheaper than one f149 :-) as I will use just one IO, there are enough IO pins to make both msp send data in parallel 8 bits to each other. Another option is to put an 16450 UART in the PCB... Thanks for the hints, folks! In the next weeks I'll write again telling what I did and how it worked!
